Compressed Air Best Practices - October 2008 - (Page 20) | 10/08 | AUTOMOTIVE TRANSIT The Windshear Single-Belt, 180 mph, Rolling-Road in Concord, North Carolina. Class Zero Air MEASURES RACE CAR PERFORMANCE BY COMPRESSED AIR BEST PRACTICES™ A 4,550-pound race car is running at 170 mph and facing wind resistance of 150 mph. The car then enters a curve creating a three-degree “yaw” (the change in angle from the direction the car is headed and the air stream). The car struggles to maintain speed as the yaw changes and the dynamic down force load on the car changes. Suddenly, the driver-less car comes to a stop on the stainless-steel track. The rolling-road track is supported by a cushion of compressed air. The lights dim in the test facility and some engineers review the data on their computers. The test is over and the race team engineers have collected the performance data they needed on their race car. Sensitive compressed air pressure sensors (accurate to ±¼ lb.) have played a key role in measuring the performance of the race car. This is the type of race car testing going on at Windshear Inc, in Concord, North Carolina. 20 www.airbestpractices.com http://www.airbestpractices.com
